Answer:
Potential energy = 261.633 kJ
Step-by-step explanation:
The potential energy is the energy stored in an object due to its position above Earth's surface.
The potential energy formula is :

Where
is the potential energy
m is the object mass
g is the gravity
and h is the height referred to a comparison plane
We start by converting the height in feets to meters


and


Where

N is Newton

J is Joule. Joule is the energy unit

We divide it by 1000 to obtain kJ
